[mautematico]

Support plan

• is this issue currently blocking your project? (yes/no): yes
• is this issue affecting a production system? (yes/no): no

Context

• node version: LTS
• module version: 2.1.1
• environment (e.g. node, browser, native): node
• used with (e.g. hapi application, another framework, standalone, ...): hapi application
• any other relevant information:

What problem are you trying to solve?

According to documentation:
https://hapi.dev/module/jwt/api/?v=2.1.1#Key-algorithms-supported-by-jwt

supported public key algorithms are:

algorithms: ['RS256', 'RS384', 'RS512', 'PS256', 'PS384', 'PS512', 'ES256', 'ES384', 'ES512'];

it would be nice to also have support for EdDSA. Has it been considered on the roadmap? Is this something of your interest? it would be awesome to have hints on where it is needed to dig deeper to make it happening

Do you have a new or modified API suggestion to solve the problem?

No

[kanongil]

Yeah, not all algorithms from https://www.iana.org/assignments/jose/jose.xhtml are supported.

If someone is interested in implementing this, it is specified here: https://datatracker.ietf.org/doc/html/rfc8037

I can volunteer to try and put up a pr for this, haven't implemented RFCs before but will definitely give a try

[mautematico]

would you please take a look at #53?

Thanks a lot for the PR, it's now released.
